Liu Yingying grew up poor, so her mind is always occupied with how to make money.
One day, Liu Yingying suddenly awakens to the truth: she's the villainous supporting character in a book, and if she interferes with the relationship between the male and female leads, she'll never make money. Liu Yingying isn't even afraid of dying; she's only afraid of being broke. After all, in this world, you can't get anywhere without money.
Every day, Liu Yingying avoids the male and female leads, terrified that they'll ruin all her hard work toward a better life.
Still, other people's childhood friends can enjoy sweet romance, so why does my childhood friend have feelings for me too? Lu Yanci, shouldn't we be working together to get rich? Why are you coming over to my house?
To Lu Yanci, Liu Yingying is the most wonderful person in the world. She is always kind to others and never loses her love of life.
